Fortunately, this kind of heavy asset investment does not need to be done once a year. Instead, an investment will benefit you for a lifetime and can even be passed on to future generations with almost no depreciation.
Similar to the spell book, there is the mage tower, but the mage tower is more "heavy".
Even Xia Duo has not considered building his own mage tower at this stage. It is too expensive. Even with Niya's help, it is difficult to raise the down payment for the mage tower.
Just from the fact that a major overhaul of the Tower of Time costs nearly one million gold coins, you can already tell how much it costs to build a mage tower.
Of course, the Tower of Time is somewhat special. Not counting the plane exploration array, multiple sets of equivalent backup arrays of different levels make its construction cost more than ten times higher than the normal version.
For an ordinary mage tower, one million gold coins can be used to start construction. Qian Niya should be able to cobble together this, but Xia Duo is not willing to make such excessive demands.
In reality, no matter how close Niya is to him, she must also consider the sustainable development of the Tower of Time itself. If she really wants to desperately raise money for Xia Duo, then Xia Duo really doesn't dare to ask for it.
For such an irrational person, God knows what unexpected actions he will make in the future. If he turns dark one day, Xia Duo will not doubt it at all.
Fortunately, although Niya is occasionally childish, she does not have yandere attributes. She is still a normal woman with normal thinking, normal rationality, and normal emotions. Well, she is also very beautiful.
Otherwise, Xia Duo would have thought about running away long ago.
…
Putting away the spell book, Sha Duo followed his body's instinct to summon a clean water ball. As soon as the water ball appeared, it trembled and moved towards Sha Duo, rolling back and forth on him.
After a while, Xia Duo's whole person was renewed and energetic, and the sloppiness of many days of "retreat" was gone. Then he called the tower spirit to cancel the "no disturbance" status.
"Xia Duo, you finally came out!"
As soon as Sha Duo's authority status in the Tower of Time was restored, Niya came directly to the door and looked at Sha Duo nervously: "Is the spell book completed? Are there any materials missing?"
"No shortage, I've finished it."
Shado comforted Niya and sat down first, then asked: "How many days has it been? Has Lord Rodney sent out an invitation?"
As long as there are no special operations, the sixth floor of the Tower of Time has constant temperature and constant light. During the "retreat" period, whenever Xia Duo feels a little tired, he will perform [Deep Sleep] on himself.
At first, after he woke up, he would ask Talling about the current time and date, but later he didn't bother to ask. He wouldn't go out until he was done, so he lost the concept of time.
Out of respect for Xia Duo and the habit of high-level mages to avoid detection, Niya did not know the specific behavior of Xia Duo during this period.
After listening to Xia Duo's inquiry, Niya felt a little strange. She looked at Xia Duo carefully and did not find any signs of poor condition in Xia Duo that caused him to ignore the time. However, she still answered seriously:
"Four days have passed since Archmage Greta left, and Lord Rodney's invitation has not been sent."
Just as she was speaking, Niya suddenly seemed a little embarrassed. She quickly looked away from Sha Duo, lowered her head and explained softly: "I have contacted the teacher, but the teacher did not reply."
Xia Duo was stunned for a moment, then realized what Niya meant, and couldn't help but feel a little moved, "There is no need to disturb Her Royal Highness, I believe that since Archmage Greta said there is no danger, there will definitely be no danger. Besides,
I will be fully prepared myself, so you don’t have to worry.”
Niya hummed and didn't speak, but she didn't leave either. She just looked at the ground not far away, wondering what she was thinking.
cough--
"Niya!"
Xia Duo shouted softly, and when Niya looked over, he said in a somewhat disgraceful tone: "Do you know of any silver or light gray dye that is not easy to fade?"
"ah--"
A surprised cry came from Niya's mouth. She obviously didn't expect Sha Duo to ask such a question, so she wanted to confirm again:
"Xia Duo, are you looking for dye?"
"right!"
Xia Duo took out the spell book that he had made before from his personal space. He did not hand it to Niya, but just shook it in his hand. The blue color, which was obviously the original color of fine gold, looked more eye-catching at this moment than before:
"This is the spell book I made, but I don't really like the color. I want to change it to a more low-key one."
Xia Duo didn't know much about the dyes in this world, including the dyes on the earth. At this time, he turned to Niya for help, and he just caught one person and asked.
Looking at Xia Duoyou's blue spell book with obvious metallic luster, Niya's expression was quite strange, "You use fine gold as the sealing material? Do you still want to use it to hit people?"
However, she did not want to interfere too much with such a personal item as the spell book. Instead, she carefully thought about which dye could last on the surface of fine gold for a long time.
After thinking for a moment, Niya gradually frowned. In her memory, there seemed to be no silver or light gray dye that could last long on the surface of fine gold.
"Sorry Xia Duo, I can't think of any dye that can last for a long time on the surface of fine gold. I'll ask other people for help, but I don't think there is much hope of finding it."
After hearing this answer, Xia Duo was still a little disappointed even though he had been mentally prepared before. However, the color of the equipment was secondary after all, as long as it functioned normally.
Just when Shado was about to give up painting the spell book, a sudden inspiration flashed in his mind, and he thought of a person - the dwarf Broto who had slayed the dragon with him not long ago.
You may not be able to find dyes that can color the metal surface, but that doesn't mean there's no way to change the color of the metal surface.
The so-called coating is not simply adhesive dyeing, but also directly changes the color of the metal itself, such as the plating on the earth, which changes the color through chemical reactions.
Although chemical reactions with electromagnetic properties on Earth do not exist in this magical world, similar elemental reactions are very common.
For example, the transmutation of mithril means that the energy of different elements continuously circulates, hedges, and transforms in mithril components, causing a small amount of mithril to change into other substances, thus reducing the purity of mithril, which in turn affects the content of mithril components.
Energy moves.
As a master blacksmith in the magical world, the dwarf Broto should be quite familiar with the various reactions of these metals. Perhaps he has a way to coat the surface of fine gold with a heterochromatic film that can hide its blue color.
You may also be able to choose colors, or even customize patterns!
Thinking of this, Xia Duo couldn't help but look forward to it. Of course, there was no need to give up on Niya's side. If he could find a more convenient dye, he would still choose to use the dye.
After all, in many cases, convenience is enough to outweigh everything else.
Even if he can't find any way to change the color, he won't be unable to accept the current spell book, but if conditions permit, it would be more pleasing to the eye to change the color.
